' Specification of Letters l'atent. Application filedMay a4, 1912.Serial. net-99,581,

To all whom it may concern:

Be it known that I, RICHARD Lnsran W na citizen of the United States,residing at Waterbury, and State of Connecticut, have invented certainnew and useful Improvements in Blank- Holding Devices, of which thefollowing is a specification, reference being had therein to theaccompanying drawings.

, My invention relates to a new and improved blank holding device,referring more particularly to mechanism for receiving blanks from ahopper chute and both holding andguiding them until they have beenproperly alined between thread rolling dies or similar operating tools,it being the object of my invention, among other things, toconstructsuch a device so that it may be secured to a fixed part andadjustable to accommodate blanks of various diameters, that are heldagainstupward movement.

To these, and other ends, my invention consists in the blankholding'device, having certain details of construction and combinationsofjparts, as will be hereinafter described, and more particularlypointed out 'in'the claims.

Referring to the drawings, in which like numerals of reference designatelike parts in the several figures: Flgure 1 isa front view of myimproved device, showing a fragmentary portion of the hopper chute towhich it is connected; Fig. 2 is a plan view thereof; Fig. 3 is a sideview looking toward the right of Fig. 1; Figs. 4 and 5 are plan views oftwo forms of the outer supporting plate; and Fig. 6 is a front view ofthe cap with a modified form of pressure mechanism.

In the drawings, the numerals 1 and 2 designate the side plates of achute leading from a hopper (no-t shown) and '3' is the cover thereof,which is held above the side plates 1 and 2 so as to leave room for thehead of the blank to-pass thereunder with the shank between the plates 1and 2, substantially as shown by broken lines in Fig. 3. The detailedconstruction of the chute and cover is not shown herein, as itconstitutes no part of my present invention.

To one of the side plates I have aflixed the body member 4, preferablyby a screw 5 and dowel pins 6. Upon the top side of the outer endthereof is adjustably secured the cap 7, having a tongue 8 upon itslower end,

in the county of New Haven which enters acorresponding' recess inthe topof the body 4, and is thereby held against lateral movement.

screw .9 pass ng- Patented Dec. 10, 19,12;

through a slot 10 in the cap 7, and threaded a 7 into the body 4:,provides means for adjus ably securing the said cap in anylof itsadusted [JOSH-10118:: Fixed to the underside of the body member 4. bythe screw 11, is the inner supporting plate 12, the, end -ofwhichprojectsbeyond the body membenas particularly shown in Fig. 3. The outersupporting plate 13 is provided-witha tongue v 14, which enters acorresponding groove in the cap 7, and is adjustably secured thereto.

by a screw 15, which passes through the slot 16 and is threaded intosaid cap. The lower end of the plate13' is provided with an inwardlyprojecting lip 17 of substantially of which is cu'rved at 18 to form acontinuation of the side' plates 1, as shown in Fig, 2.

In practice, the plates 1 and 2 are placed in relation to each other sothat there is blank to pass easily therebetween, and as the plates areadjustable toward and away from each other blanks of various diametersare accommodated. The open-space between the plate 12 and the lip 17should be the same as that between the plates land 2, and this isaccomplished by shifting the endwise position of the plate 13 upon thecap 7, so that the'end 18 moves toward and away fromthe body 4, andoutwardly by shifting the position of the cap 7 upon the body member 4,thus providing ample adjustment of the parts in relation to each other.1

In order that the underside of the head of the blank may always be heldin contact with the upper surface of the lip 17 and 'plate'12 whiletheblank is passing 'there through, I have provided a device whichexerts a yielding endwise pressure thereon, and comprises a plate 19,upon which is a stud'20that passes through the cap 7, a coil spring 21that surrounds said stud between said plate and the underside of saidcap, and check nuts 22 threaded on said stud to limit the movement ofsaid pressure plate in one direction.

In Fig.5 I have illustrated a plan view of the outer supporting plate 13for supporting a blank that is not to be threaded to the head thereof,and in Fig, 4 is shown .the same thicknesses the plate. 12, one end justsufiicient room for the shank of the Fig. 4 aportion of the lip 17 iscut away so as to permit the blank to drop off the lip 17 and rest onthe top of the diqs'and held there by the pressure plate 19. When body4, the outer end 26 of which during its the outer su porting plate 13 isused, the position oft e inner supporting plate 12 is reversed from thatshown in Fig. 3 so that the inner edge 27 thereof becomes the'outer edgeand is then toward the outer supporting plate and flush with the outerend of the body member 4:.

In Fig. 6 is illustrated one of, many other forms of pressure devicethat may be used equally as well as the one above described, whichcomprises a spring 23 that is secured by screws 24 to the cap 7.

A feedstop 25 is slidably mounted in the movement projects across theopen space between the plates 1 and 2, as shown in Fi 2, and .stops thefeeding of blanks throug the chute, but when withdrawn, as shown bybroken lines in Fig. 2, theblanks are free to pass by and into theholding device.

With the device; fastened as it is to a fixed plate of the chute, thecover 3 is free to be moved out of its operative position and expose thechute, whereby re airs or adjustment are facilitated, or b anks thathave been damaged orclog the chute may be readily removed;

There are minor changes and alterations that can be made within myinvention, aside from those herein suggested, and I would therefore haveit understood, that I do not limit myself to the exact constructionherein shown and described, but claim all that falls fairly within thespirit and scope. of nlly invention as set fort in the appended c alms.

Having described my invention, what claim as new and desire to secure byLetters Patent, is:'-

1, a device ofthe character described, the combination with a chute; ofabody member connected therewith; a cap secured thereto, so as to beadjustable substantially parallel with the direction of movement of theblanks within said chute; a supporting plate connected with said bodymember; and a second supporting plate secured to said cap, so as to beadjustable at substantially a right angleto the said cap.

2. In a device of the character descrlbed, the combination with a chute;of a body member connected therewith; a cap secured thereto, so as to beadjustable substantially parallel with the direction of movement of theblanks within said chute; a supporting plate connected with said bodymember; and a second supporting plate, having a lip thereon that curvesinwardly at one end, secured tosaid cap, so as to be adjustable atsubstantially a right angle to the said cap.

3. In a device of the character described,

.the combination with a chutegbf a body yielding member mounted so as tolie above the open space between said supportin plates.

4. In a device-of the character described,

thecombination with a chute; of a body member connected therewith; a capadjustably secured to said body member; a supporting plate also securedto said bod memher and projecting beyond the end t ereof; a secondsupporting plate, having a lip thereon; and a pressure device forholding the underside of the blank heads against said supporting plates,said device comprising a'plate, having a stud thereon, means forlimitingthe movement of said plate in one direction, and a springfor-normallyvmoving said plate in one direction.

In testimony whereof I affix my signature in presence of two witnesses.
